GAS-GENERATING MACHINE.

SPECIFICATION forming part of Letters Patent No. 571,221, dated November 10, 1896.

Application filed $epten1her 13,1895. Serial No. 562,368. (No model.)

To ctZZ whom it may concern.-

Be it known that I, JOHN A. EN os, of \Vashington, District of Columbia, have invented a new and Improved Gas-Generating Machine, of which the following is a full, clear, and exact description.

This invention relates to machines of a port able character for generating gas for illuminating or heating purposes.

The object is to provide a machine so constructed that there will be a constant supply of air forced through the generator, which will prevent variations of the flame; and, f urther, to so operate the generator-cylinder that all of the heavier oils will be operated upon by the air-pressure.

The invention will be fullydescribed hereinafter and defined in the .claims.

Reference is to be had to the accompanying drawings, forminga part of this specification,

in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a side elevation of a gas-generatingmachineembodyingmyinvention. Fig. 2 is a plan view thereof; and Fig. 3 is a partial section and partial elevation, on an enlarged scale, of some of the operating parts.

Referring to the drawings, A A A A designate a series of pumps, each mounted on a bed-plate A and extended vertically. Each pump comprises a shell or casing 1, having a bottom closure 2, a tubular piston 3, closed at its top and operating concentrically in the shell or casing 1, an air-inlet pipe 4, open at its top and arranged within and concentric with the piston and having an opening through the bottom closure 2 of the shell or casing 1, and an air-outlet pipe 5, placedconcentrically within the inlet-pipe 4 and of somewhat less area than the area of the pipe 4. The cylinder orcasing 1 is designed to be filled with a liquid sealing material for the piston. This liquid may be water.

The inlet-pipe 4 communicates at its lower end with an inlet-pipe 6 of large diameter, and which is here shown as of substantially S shape. Its upper end is provided with a valve-casing 7, having a perforated partition 8, arranged horizontally therein, and upon which is mounted a valve-plate 9, which is movable upward, to admit air through the perforations of the partition 8, on a screw 10,

projected from said partition 8. This valveplate consists of flexible material, such, for instance, as rubber, and it may be provided with a weight 11 to force it downward.

The outlet pipe 5 extends downward through the lower portion of the pipe 6 and communicates with an outwardly and upwardly extended pipe 12, having at its upper portion a Valve-casin g 13, in which is arranged horizontally a perforated partition 14, having a valve'plate 15, of flexible material, on its upper side, movable on a pin 16, extended from the plate, and having a weight 17 for holding it or forcing it to its seat. The pipes 12 of the pumps A A above the valve discharge into a chamber 18, and the pipes 12 of the pumps A A discharge into a chamber 19, and these chambers 18 19 are connected by a pipe 20, from which a pipe 21 extends to the generator B.

I will now describe" the mechanism shown for operating the pump-pistons.

22 designates a gear-wheel rigidly mounted on a driving shaft 23, having bearings in blocks on standards 24, extended upward from the bed-plate A The gear-wheel 22 meshes with a pinion 25, mounted on a transverse shaft 26,.having bearings in blocks on uprights 27, extended from the bed-plate A and on this shaft 26 is mounted a gear-wheel 28, meshing with a pinion 29, loosely mounted on the shaft 23. To this pinion 29 is attached a gear-wheel 30, which meshes with a pinion 31, attached to a sleeve 32, adapted to rotate freely on the shaft 26. To the other end of this sleeve 32 a gear-wheel 33 is attached, and this gear-wheel 33 meshes with a pinion 34 on a sleeve 35, mounted to rotate on the shaft 23, and to this sleeve 35 is attached a large gear-wheel 36, which meshes with a pinion 37, mounted on a shaft 38, which carries at its ends cranlcdisks 39 40.

The pistons of the pumps A A are respectively connected by links 41 42 with a walking beam or lever 43, having its fulcrum in a hanger 44, depending from a transverse bar 45 on uprights 46. The pistons of the pumps A A are respectively connected by links 47 48 to a Walkingbeam or lever 49, having its pivotal or fulcrum bearinglike the one hereinbefore described.

Extended downward from the shaft of the walking-beam 43 is an arm 50, which has a pitman connection 51 with the crank-disk 39, and the walking-beam 4:9 has a similar arm 52 depending from it, and this arm has apitman connection 50 with the crank-disk 40. To regulate the throw or length of movement of the pistons, the wrist-pins 54 for each pitman are adjustable in a transverse slot 55 in the cranlcdisks.

It will be seen particularly in Fig. 1 that the crank-disks are so arranged that the wristpin of one crank-disk will be in a position substantially at right angles to the position of the wrist-pin on the other crank-disk. By this construction it is obvious that there will be a constant operation of the pump-pistons and that at least one piston will be on the downward stroke while the other pistons are on an upward stroke, so that there will be no variation in the air-pressure or flow of air carried through the generator.

Rotary motion is imparted to the shaft 23 by any suitable motor. I have here shown a drum 56, having journal-bearings in a suit able frame, and around which a cord or connection with an operating weight is placed. At one end the drum 56 is provided with a gear-wheel 57, meshing with a pinion 58, the shaft of which has a crank 50 attached to it, by means of which the drum may be rotated to wind the cord when it is desired to start the machine in operation. As a means for preventing the rotation of the drum at any time, I provide it with a ratchet-wheel 00, adapted to be engaged bya pivoted dog 61 on the frame.

The generator B consists of a cylinder mounted to rotate on standards 62, extended upward from the bed-plate A". Arranged vertically within the cylinder B are two perforated diaphragms 63 0t, forming end chambers 65 (i6, and a central chamber 67, within which chamber a packing of absorbent material, such, for instance, as sponge in small pieces, is packed. Aifixed to one trunnion or journal of the generator-cylin der is a band wheel 68, having a band 69 extended around idler-pulleys 7 O and around a pulley 71, affixed to the shaft 23, so that when in operation the generator-cylinder will be slowly rotated. The object of rotating the generator-cylinder is to keep the heavy oil, which would ordinarily settle at the bottom of a stationary cylinder, in constant movement through the absorbent material in the generator. By keeping the oil in constant movement it will all be used in the manufacture of gas.

I find by experience that an ordinary cylinder for the generator often gets out of shape by expansion and contraction due to atmospheric changes, and to obviate these difficulties I have shown the cylinder 13 as corrugated on all its sides. The pipe 21 has a suitable valve, and this pipe 21 communicates with the interior of the generator through one of its trunnions, and the other trunnion of the generator communicates with a valved outlet-pipe 02, and a water-pressure gage 63 may be placed on the pipe 62.

In operation the air will be forced through the pipe 21, through the perforations in the diaphragm 64, and through the absorbent material 67, containing the oil, and the gas formed therein will be forced through the perforations in the diaphragm 63 and out through the discharge-pipe 62 to the place of consumption.

The machine embodying my invention, as above described, may be operated in any locality and for any lenth of time, and the consumption of oil I find in this machine is comparatively small.

Having thus described my invention, I claim as new and desire to secure by Letters Patent l. A gas-generating machine, comprising a generator cylindrical in cross-section and havin g annular corrugations on its side and end walls, perforated diaphragms in the generator, absorbent material between the diaphragms, means for rotating the generator and means for forcing a constant pressure of air through the generator, substantially as specified.

2. In a gas-generating machine, a generator comprising a cylinder of corrugated metal and mounted to rotate, perforated diaphragms in the said cylinder, absorbent material between the diaphragms, and means for rotating the cylinder, substantially as specified.

3. The driving power for a gas-generating machine, comprising a weight-operated drum, a shaft operated thereby, a gear-wheel rigidly mounted 011 said shaft, a pinion on another shaft and with which the gear-wheel meshes, a gear-wheel connected with said pinion and meshing with a pinion loosely mounted 011 the first-named shaft, a gear-wheel connected to this last-named pinion and meshing with a pinion attached to a sleeve mounted to rotate on the second-named shaft, a gear-Wheel on said sleeve connected with a pinion mounted on a sleeve adapted to rotate on the firstnamed shaft, a large gear-wheel on this last named sleeve, a pinion with which this lar e gear-wheel engages, and crank-disks on tne shaft of said pinion, substantially as specified JOHN A. ENOS. IVitnesses CHAS. II. B'URLEIGH, GEORGE PEIRCE.
